Accounting Statistics (2026): Industry Size, Talent Gap & AI

The US accounting industry has never been bigger. Accounting services generated $145.5 billion in revenue in 2025, an all-time high, spread across roughly 137,000 firms employing 1.6 million accountants and auditors. Unemployment in the profession sits near 2%, which is about as close to full employment as a job market gets.

The problem is supply. Employers need about 124,200 new accountants every year. American universities graduate roughly 55,000. Accounting degrees just hit a 20-year low, CPA exam candidates are down about 30% since 2016, and around three quarters of working CPAs are near retirement age. The math does not close, and it has not closed for years.

So the profession is automating instead. Nearly half of accountants now use AI every day, up from 18% in 2023, and the single most common thing they point it at is pulling data out of documents. In this article, you’ll find how big accounting is, how deep the talent gap runs, how fast AI is actually arriving, and how much of the job is still manual data entry.

How big is the accounting industry?

The striking thing is how fragmented it is. The average US accounting establishment employs fewer than 10 people, so behind the Big Four sits a very long tail of small firms and solo practitioners. Deloitte, PwC, EY, and KPMG together booked over $220 billion in global revenue in 2025 and employ more than 1.5 million people worldwide, with Deloitte the largest at $70.6 billion. Everyone else is running a small business.

That shape mirrors the industry accountants serve. Roughly 4,300 banks are left in the US, yet the four largest hold close to 40% of all banking assets: concentration at the top, a long tail underneath, in both cases.

How many accountants are there in the US?

About 1.6 million accountants and auditors held jobs in 2024, earning a median wage of $81,680. Roughly 665,000 hold an active CPA license, though that count varies by source depending on how licenses in multiple states are handled. Another 1.3 million people work as bookkeeping, accounting, and auditing clerks, and women make up about 60% of the accounting workforce — one of the few professions where they outnumber men.

Employment is projected to grow 5% from 2024 to 2034, faster than the average for all occupations. Demand is not the issue here.

Is there really an accountant shortage?

Yes, and the arithmetic is blunt. The BLS projects about 124,200 openings a year through 2034, mostly from retirements and people leaving the field. US universities produce roughly 55,000 accounting graduates a year, and not all of them become accountants.

Every part of the supply side is shrinking at once. Accounting graduates fell 6.6% in the 2023–2024 academic year, after a 9.6% drop the year before, with master’s degrees down 15%. That leaves graduate numbers at a 20-year low. CPA exam candidates have fallen roughly 30% since 2016, when 48,004 people sat for the first time. And about 75% of active CPAs are near retirement.

Firms feel it. Over 90% of finance leaders report difficulty finding qualified staff, roles requiring a CPA take about 73 days to fill, and 77% of firms are considering or already using offshore accountants. There is one early hint of a turn: accounting program enrollment rose double digits in the 2024–2025 year.

Why are accountants leaving the profession?

Because the job asks a lot, in a compressed window. During the 2024–2025 busy season, 48% of public accountants worked 51–60 hours a week, 19% worked 61–70, and 12% logged more than 70. Predictably, 88% say they want better work-life balance and 87% want fewer hours.

The exits follow the calendar. Public accounting turnover runs 15%–22% a year, and about 84% of those departures are voluntary. First-year attrition is the worst at 25%–35%, and April through June — right after busy season ends — accounts for close to half of all voluntary departures.

How many accountants use AI?

This is where the data gets genuinely messy, and it is worth being honest about it rather than picking the most dramatic number. Depending on which 2025 or 2026 survey you read, AI adoption in accounting is anywhere from 41% to 97%.

Why the numbers disagree so much: these surveys are not contradicting each other so much as measuring different things. Some ask individual accountants, some ask firms, and some ask corporate finance departments, which are much larger and better resourced. And “uses AI” can mean anything from a partner asking a chatbot to reword an email once a quarter, to a firm running autonomous reconciliation. Surveys asking about any use, ever land near the top of the range; surveys asking about daily use land near the bottom. Treat 46% daily use as the conservative floor and the high nineties as “has touched it at all.”

What is not ambiguous is the direction. Daily use went from 18% in 2023 to 46% in 2025, and firms that have deployed AI report a 30% faster month-end close and 25% more advisory revenue. That last part is the real prize: advisory work bills at rates 40% to 60% higher than compliance work, so every hour automation claws back from grunt work is worth more when it comes back.

How much time does manual data entry cost accountants?

More than you would expect for 2026. About 30% of accountants still spend more than a full week each month on reconciliation alone, and 83% of knowledge workers say they lose too much time to manual entry that could be automated.

It costs a firm roughly $6 to $15 to process a single bank statement by hand, depending on transaction volume. That cost is why document work became the first thing accountants automated, ahead of the flashier uses — turning a statement PDF into clean rows is exactly the kind of drudgery a PDF-to-CSV converter removes.

The accuracy argument helps too. Manual entry carries an error rate of roughly 1% per field for skilled operators and up to 4% for average ones, while automated extraction now lands in the same range as experienced humans, without the fatigue. For a small business doing its own books, the arithmetic is starker still: manual processes eat about 10 hours a week, or more than 500 hours a year.

Do small businesses even use accountants?

Often, no. Roughly 70% of small businesses do not have an accountant, about 34% of owners handle the bookkeeping themselves, and around 72% of self-employed people do their own. Software fills much of that gap, with about 64% of small business owners using accounting software and QuickBooks holding roughly 62% of the market.

That do-it-yourself majority is not always confident about it: 21% of small business owners admit they do not know enough about bookkeeping. It is a familiar pattern in small-business banking, where the practical setup is usually simpler than the professional advice suggests — much like how many bank accounts people actually keep.

How much do businesses lose to fraud?

The typical organization loses about 5% of its revenue to fraud each year, according to the ACFE’s biennial study of nearly 2,000 real cases across 138 countries. The median case costs $145,000, and total losses in the study period ran past $3.1 billion.

The pattern is the inverse of what most people picture: the most common fraud is the cheapest, and the rarest is by far the most expensive. It also dwarfs the crime that gets the movies. A median fraud case costs a business $145,000 and takes a year to detect, while the average bank robbery nets a few thousand dollars and gets solved about 60% of the time. The money leaves through the accounting department, not the front door.
